Yii set default value in model rules

The yii default rule only works if there is no database default value set for the field. Therefore you should either set the default in DB or in Model rules like

   array('active','default', 'value'=> 1, 'setOnEmpty'=>TRUE),

Ubuntu permissions for web directory /var/www

To best share with multiple users who should be able to write in /var/www, it should be assigned a common group. For example the default group for web content on Ubuntu and Debian is www-data. Make sure all the users who need write access to /var/www are in this group.

   sudo usermod -a -G www-data 

Then set the correct permissions on /var/www.

    sudo chgrp -R www-data /var/www
    sudo chmod -R g+w /var/www

Additionally, you should make the directory and all directories below it “set GID”, so that all new files and directories created under /var/www are owned by the www-data group.

   sudo find /var/www -type d -exec chmod 2775 {} \;

Find all files in /var/www and add read and write permission for owner and group:

   sudo find /var/www -type f -exec chmod ug+rw {} \;

You might have to log out and log back in to be able to make changes if you’re editing permission for your own account.
